The Processing and Fusion on Low Light Level Image and Infrared Thermal Image

In this paper, on the base of analysis on low light level (LLL) image and infrared (IR) thermal image's characteristics, the researches on the processing and fusion on LLL and IR image has been done. The dual-channel image registration techniques of LLL and IR image are put forward, including digital real-time shift technique and dual-channel fusion stereoscopic color display technique. The color night vision information acquiring and processing system of LLL image (0.4 ~ 0.9nm) and infrared thermal image (8 ~ 14nm) is developed. The systematically experiments have been carried out and some good results have been obtained. This LLL and IR image fusion color night vision system can effectively increase the discovery and recognition probability of object from its background
